5.0 Jesse S. Uncadville, CT

Sullivan construction was one of the easiest, most straight forward, and honest companies I have had the pleasure of working with. Even with unforseen complications brought on by the pandemic they showed nothing but professionalism, politeness, and top quality workmanship. They completed the job from start to finish in a single day, which was astonishing, and then still had the dedication to send out one of the owners the next day to check on my satisfaction with the work they had done. They did great work at a fair price, and I would wholeheartedly recommend them to anyone who is looking for a stress free professional experience with a contractor. 5 out of 5!

5.0 James K. Essex, CT

Highly recommend doing business with Sullivan. They were very accommodating, especially in light of the weather challenges we faced. Their work crew was fantastic. Overall really impressed and satisfied with the job.

5.0 Peter N. Groton, CT

Totally satisfied. Did the job in one day instead of two like I expected. My only issue I have is with the company hired for the dumpster, it's been sitting in my driveway for four days now.

5.0 Carmine T. Putnam, CT

This was an awesome experience from start to finish. From 1st contact and estimate to finish the total job. There were many challenges with the world situation and materials, unexpected work needing to be done and their own vehicle breakdowns, it did not deter them. They finished in our agreed timeframe to fit around my vacation week. I will definitely be hiring them for more projects and recommending them to others.

5.0 Tatashi H. Columbia, CT

My husband and I were very happy with the job this company did on our roof and shed roof. When the shed roof was being replace there was some frame work that had to be repaired. I was really impressed with how it turned out. We would definitely use them again for future projects we want done.

5.0 Pierre F. Uncasville, CT

Sullivan construction did my roof this week. George did a very nice and it was done in one day. I love it and they do not require a large amount for a deposit, you pay them after the job is done after doing a walkthrough with the owner. I will definitely recommend them to anyone who needs their roof done.

5.0 Cheryl L. Danielson, CT

I was extremely happy with the work done. They replaced my entire roof in 1 day,including replacing 6 sheets of plywood and fixing the chimney. Fantastic!

5.0 Jo-ann M. Brooklyn, CT

George is super friendly and knowledgeable and the team came in and got it done! They cleaned up every scrap of material, raked the flower beds, and left the yard neater than when they arrived. Highly recommend!!

5.0 Susan B. Westbrook, CT

I had some real losers quote redoing my dormer. I was so stressed out Iâ m women alone. A few of them tried to take advantage of me. Sullivan was fast and good. George knew my dormer was leaking, and came quickly. I will be hiring Sullivan to do more work to my house. Couldnâ t ask for a nicer man then George Sullivan.

5.0 Charles J. Gales Ferry, CT

gave a fair realistic quote first time! when they did the JOB it was FAST! and Professional!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
